In the last decades, very detailed work has been carried out on the classical electrophoresis of enzymes and isoenzymes. Despite modern PCR techniques, enzymes remain important as post-transcriptional and translational products of an organism's DNA and as enzymic and structural components of the cell. This book compiles facts and methods on classical and modern techniques of enzyme and protein electrophoresis widely dispersed in hundreds of publications. The author summarizes them in clearly readable tables, in many carefully worked out separation- and more than 140 staining protocols. He also supports the reader in the interpretation of enzyme patterns with respect to population genetics and evolutionary studies. Illustrations and marginal notes facilitate quick and informative reading. . The exhaustive practical experience of the author and the wealth of material summarized and reviewed make this book a "must" for every enzyme laboratory. It will supply the practitioner with profound information on state-of-the-art enzyme electrophoresis.
